ATTACHMENT FOR ELECTRIC METERS.

Specification of Letters Patent.

Patented July 2, 190'].

To all whom it may concern:

Be it known that I, WILLIAM L. Sanvnnns, a citizen of the United Still-cs ol' gunorica, residing at Denver, in the county of Denver and State of Colorado, have invontcd certain new and useful Improvements in Attachments for Electric Motors, of which the following My invention relates to an attachment for electric motors, its object being to frustrate and detect any atlclupt made by unautl'iorizcd or maliciously inclined persons at tampering with the exposed portions of the so-callml loop wires which extend from the wall to the electric meter.

To this end I provide a suitable, preferably metal covering, which; inclosing the exposed portion of the above named wires, may be scaled by the person or company furnishing the electricity, the consumed quantity of which is measured by the meter. The seal, which may bear the companys imprint, must be ruptured in the act of uniastening or removing the casing and thus indicates the fact of its being improperly opened or tampered with, which leads to the ready detection of any attempt made to reach the incloscd wires. In case the covering incloscs the lower part of the meter, as in the form illustrated in the accompanying drawing, an incidental advantage is gained by its rendering the screws which secure the cap of .the meter to its back plate inaccessible and preventing unauthorized opening oi the meter-casing.

Having thus briefly explained the objects and. nature of my attaclnnmit, I will now procecclto describe the same in detail, reference being had to the acconr panying drawings in the several views of'which, like parts have been similarly designated and in which,

Figure l-represcnts a front elevation of an electric meter provided with. my attachment, the loop-wires being shown in broken lines, Fig. 2a side elevation of the same, Fig. 3a perspective interior view of the attachment, Fig. 4-a similar exterior view of the same, and Fig. 5-one of the screws used to secure my attachment to the meter. I Let 5 designate an electric motor attached to the wall 6 by screws or nails 7 and 8. 9 and 10 are theloopwires which lending to and from the meter form part of the main circuit through which the current of cloctricity flows from the generating station to the consumer. Wires 9 and 10 have been shown to pass through the. wall at points 11 and 12 and to enter and leave meter 5 at 13 and 14.

l5 dcsignatcs my attaclnncut which consists of a suitable casing or covering adapted to inclose the exposed parts of wires 9 and 10 and hold in its normal position by headed screws 16. Screws 16, passing 'tlu'ongh apcrtiires 17 in the ro ing, ore cred a convenient portion of thenr or ii nec the wall against which the meter is placed. Casing 15 consists of a iront plate l5 and an integral surrounding side 15, a recess 15 being cut in its upper portion, which permits it to embrace the lower part of the metor-cap 5. Extending outwardly from front plate l5 in alinement with the bolt holes 17, are apertured lugs 18 which afford means to seal screws 16 after the casing has been placed in position. The sealing is effected by'a cord or wire 19, which passes through the apertures l8 in lugs 18 and corresponding holes 16 in the heads 16 of the screw-bolts 16. The ends 19 of wire 19 are brought together as at and united by a seal 20, made of lead, or other suitable substance ancl'which as explained, may bear the imprint of the owner or owners oi the meter.

It should be understood that the form and arrangement of the casing may be varied to conform with differently constructed meters or to inclose the wires in case they enter or leave the meter at different points from those shown in the drawings.

The bolts or other fastenings employed to secure the attachment may also be sealed in any convenient manner and within the spirit of my object, viz.- to frustrate tampering with the exposed parts of the loop wircs between the wall and the meter by insuring detection of any attempt thereto.

Having thus described my invention what I claim is 1. The combination with an electric meter having serv' .ice ,wires emerging therefrom of detachable casing arranged to lllil0S8 i'llG exposed portions of the said wlres extending between the meter and the wall against which? it is placed.

2. The combination with an electric meter having some ice wires emerging therefrom of a suitable covering adapt ed to inclose the portions of the said wires extending be tween thcmetcr and the well against which if: is placed, and means to' detect removal of said covering.

3. The combination withhn electric meter having serv-, ice wires emerging therefrom of a. casing adapted to inclose the portions of the said wires extending between the meter and. the wall against which it is placed, means to secure said casing, and means to detect removal of said securing means.

4. The combination with an electric meter having servcasing adapted to. in

ice wires emerging therefrom of a close the portions of the sold wires extending between the meter and the well against which it is placed, screw bolts securing said casing, and means to seal said bolts.

5. The combination witirnn elecilic meter of a casing adapted to lnclosc the and having. apertured securing said casing,

'projections; apcrtured screw bolts a cord extending through the apertures of sald"projectlous and bolts, and means to unite Witnesses .ssar in i .T. ltonranonr, K. M. EDP-UMP,
